合成了对叔丁基杯 [8]芳烃乙酸衍生物。在 (30± 1 )℃ ,I =0 1mol/kg条件下 ,研究了它对Fe3+ 、La3+ 的萃取性能 ;用斜率法研究了萃取反应机理 ,得到了萃取反应平衡常数 ,并发现该萃取剂对Fe3+ 、La3+ 存在着两种不同的萃取机理。
P-tert-Butylcalix [8] areneacetic acid derivatives were synthesized. Under the condition of (30 ± 1) ℃, I = 0 1mol / kg, the extraction performance of Fe3 + and La3 + was studied. The extraction reaction mechanism was studied by the slope method and the equilibrium constant of extraction reaction was obtained. There are two different extraction mechanisms for Fe3 + and La3 +.
